The agreement between Turkey and the United States to push U.S.-allied Kurdish militiamen out of Syria’s Manbij region is delayed, “but not completely dead,” Turkish President Recep Tayyip Erdogan declared, the Hurriyet newspaper reported on Thursday.

Erdogan reportedly made those comments while traveling back from a visit to Hungary on Tuesday.

In recent weeks, Turkey has accused the United States of delaying the withdrawal of the Kurdish People’s Protection Units (YPG) from Manbij as part of the deal.

Following months of a stand-off between fighters from the U.S.-backed SDF, predominantly made up of YPG fighters, and Turkish-allied opposition fighters, Turkey and the United States reached an agreement to reduce tensions in May.

Turkish and American forces have already begun conducting coordinated but independent patrols in Manbij as part of the deal, Reuters noted.
